Mercedes driver Nico Rosberg has put his car on pole position for tomorrow's Belgian Grand Prix at Spa.

The current drivers' championship leader finished just ahead of teammate Lewis Hamilton in qualifying this afternoon.

A heavy shower shortly before the start of the session left the longest track on the Formula 1 calendar in a wet condition for qualifying.

Red Bull's Daniel Ricciardo tried to split the Mercedes cars late on, but struggled to match their pace in the damp conditions, running wide on his final lap to finish fifth.

Current world champion Sebastian Vettel will start from third, alongside Ferrari's Fernando Alonso on the second row.

Sauber's Esteban Gutierrez failed to progress from the first part of qualifying, having broken down after setting only one flying lap.

Andre Lotterer, who is replacing Kamui Kobayashi for just one race, outqualified Caterham teammate Marcus Ericsson on his F1 debut.
